I have an office where we replaced their existing switches with 3850 switches and we are using Auto QOS.  Once the replacement was done, we started to see discarded traffic from our NMS.  In troubleshooting the issue, I noticed on some of the trunks class-default traffic was being dropped.  I compared the policies from one site to another, and they are identical.  The only difference I have been able to find is that in the office where we are having the discards, none of the trunks between switches are locked to 1000/full.   Can this affect QOS if they are set to auto/auto?  I went through some AutoQOS info from Cisco and they don't talk about setting port speed/duplex. Thanks. ... View more

I have a six switch 3850 stack that has been in production for over a month now, and everything is running normal.  Last week, hosts plugged into one of the switches stopped working, the hosts are not getting an IP address (this is access layer so PC's and phones).  In addition, if I look at the MAC address table for a port, I am not seeing a MAC  address.   All of them are running 03.03.03SE        cat3k_caa-universalk9 .   I am thinking this is hardware related, only because on occasion I see the following messages in the logs: Dec 17 12:21:18.052: %IOSXE-3-PLATFORM: MEMBER: 5 process fed: : -Traceback=1#88b11e4e26f5ac75f4f2f18f023e5220   :550E7000+3B9240 ngwcutils:2AF2C000+BE94 ngwcutils:2AF2C000+DA9C pthread:2E3C2000+5DC8   Also, I have a phone in a port on this switch for troubleshooting.  When I removed the service-policy from the port to rebuild the port configuration, I received this message: %FED_QOS_ERRMSG-3-QUEUE_BUFFER_HW_ERROR: MEMBER: 5 fed:  Failed to allocate buffers for Gi5/0/1: code 18.       ...

I have a 3850 switch stack (6 switches) running 03.03.03SE   cat3k_caa-universalk9.  This week, all of the devices in this switch logs network connectivity.  When these devices are moved to another switch in the stack, they work as expected.  The stack ports show ok and are connected correctly. If I look at a port where a device is connected, it shows connected, and in an up/up state.  However if I look at the port for the device MAC, no MAC is present. I am guessing it is hardware related.  In the logs, I see entries like this.  In the last hour and half, I have seen messages similar to this three times.   Dec 11 14:21:31.944: %IOSXE-3-PLATFORM: MEMBER: 5 process fed: : -Traceback=1#88b11e4e26f5ac75f4f2f18f023e5220   :546C6000+3B9240 ngwcutils:2B8A2000+BE94 ngwcutils:2B8A2000+DA9C pthread:2ED38000+5DC8   ...

I have a stack of 7 3750x switches connected via Stackwise (one logical switch).  Within this switch, I have created to powerstacks (4 switches in one, 3 in the second stack).  Here is my configuration: stack-power switch 1  stack Powerstack1  standalone stack-power switch 2  stack Powerstack1  standalone stack-power switch 3  stack Powerstack1  standalone stack-power switch 4  stack Powerstack1  standalone stack-power switch 5  stack Powerstack2  standalone stack-power switch 6  stack Powerstack2  standalone stack-power switch 7  stack Powerstack2  standalone   When I issue the command "Show stack-power", it looks like the stack name has changed.  Before I noticed the stack name change, I noticed that all of the stack power ports were not enabled, so I went through and enabled all of them.  In fact, when I first noticed those ports were not enabled, the output for "show stack-power" had many entries for different Powerstack (see second chart).  Any suggestions on how to fix this?  I haven't rebooted the stack yet which I have a feeling will resolve it.

Hi, We are in the process of installing QOS Policy Manager and I am struggling with a simple way to import devices into Common Services 3.2.  The interface and the documentation is lacking to say the least.  If it helps, we have a separate installation of Ciscoworks LMS 4.1.  If I can run an export from that and than import into Common Services, I think that would be the easiest way to get all of my devices. We use Solarwinds Orion for network monitoring, and I was hoping this application had something similar where you could do a device discovery via scanning a subnet via SNMP.  If this is available, I don't see where to set this up. I did manually add a device, and I thought about exporting it and building a csv file from the headers from that file, but we have so many devices that I feel that would be very time consuming to build that list. Any suggestions?                   ... View more
